    /// recieve a 302 object moved status code. This issue has been confirmed by the Microsoft ASP.NET 
    /// team. To fix this issue in CS 2.x, it is necessary to use the RewritePath overload of
    /// (string, string, string, bool). Unfortunetly, this overload is not available in .NET 1.1. 
    /// 
    /// If no provider is specified in CS, CSUrlReWriter is used. To ease configuration, before declaring
    /// the default type, CS will check to see which verion of HttpContext is used. If the Major version is 
    /// greater than or equal to 2, we will dynamically instantiate the CSASPNET20UrlReWriteProvider instance
    /// instead.
    ///
